Preparing the USB stick
Download all needed software to the computer you will use to prepare the USB stick.
The USB stick will be erased. So save any contents you might want to keep.
- Start Disk Uitility
- Select the Stick itself. If your stick is already formatted it may show multiple lines. Select the first one. It usually named after the product. In my case it's SanDisk Extreme
- In the bottom right corner of the main window the Device: can be found. It will be something like disk1. Note the value.
- Select Erase
- Name: a
- Format: OS X Extended Journaled
- Scheme: GUID Partition Map
- Press Erase
- Quit Disk Utility
- Open Terminal
- enter the following. This is all in one line. When entered press the <Return> key.
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --volume /Volumes/a
- Enter <Return>
- Enter Password
- Enter Y
- Enter <Return>
- Wait this will take a while - using a fast USB stick pays off here.
- When finished enter (you will need the device noted above, preceded by /dev/ and succeeded by s1).
diskutil mount /dev/disk1s1
- Enter <Return>
- You will see a new Volume called EFI in the side Bar of your Finder window.
- Rename it to INSTEFI. This is not strictly needed, but will help to distinguish the million of EFI volumes floating around.
- Start Clover
- Advance by pressing Ok to step Installation Type
- Change Install Location to your Install stick (Install OS X El Capitan)
- Customize
- Select Install for UEFI Booting Only
- Drivers64UEFI
- Select OsxAptioFix2Drv-64
